Aggregation pheromones of Drosophila immigrant, D. phalerata, and D. subobscura

Summary, in English

Aggregation pheromones of Drosophila immigrans, D. phalerata and D. subokscura were demonstrated by testing attraction of adult flies to hexane extracts of the flies in a windtunnel bioassay. Extracts of adult males of all species attracted conspecific males and females. However. D. suhobscura flies were attracted only when the extract was applied on food. GC-MS analysis identified (Z)-11-octadecenyl acetate (cVA) in the extracts of adult male D. immigrans and D. phalerata. Both species were attracted to synthetic cVA. Male and female D. subobscura produced 5,9-pentacosadiene, 5-pentacosene, 2-methylhexacosene and 5.9-heptacosadiene. while only male D. subobscura produced (Z)-5-tricosene and minor amounts of cVA.
